Hi ksaltik
If you add raw materials or product parts to final products, the purchase price of the final product can be set from the cost of the BOMS, but not the regular price.
Also, I apologize but for now we don't support multi-currency. In any case, if you would like to add this feature you may use custom development, but as we don't offer this service you will need to hire a developer.
Best Regards,
Andrea.
